This invention is an improvement in binder boards for shingle bundlesand the like, and particularly in binders of paper board and the like.

6 Boards of the character in. question are adapted .for use with bundlesof shingles,

usually of composition material. One board is arranged at each end ofthe bundle, and

they are bound together with the shingles- Q by means of flexiblestrands, as for instance cor'ds or wires.

The strands must be drawn tightly to hold the bundle in compactcondition, and the shingles against displacement, and the strands tendto cut or otherwise damage rovide a board, composed of relatively.

ight material and of asingle thickness of such material, having meansformed from the board itself and integral therewith for reinforcing theboard against acutting .action of the strands.

With this and other objects in view, the invention consists in theconstruction and novel combination of parts fully described hereinafter,illustrated in the accompanying drawings, and pointed out in the claimsvarious changes in the form, proportion, size and minor details ofconstruction, within the scope of the claims, may be resorted to withoutdeparting from the spirit of the invention.

In the drawings: Fig. 1 is a perspective view of a bundle of shinglespackedwith the improved binding boards.

In the present embodiment of the invena section ,on the line 22 of o'fthe board. The area within the crease lines appended hereto, it beingunderstood that tion the improved board is shown in connection with abundle of shingles indicated at 1+the boards forming the subject matterof the invention being arranged at opposit-e ends of the bundle.

Each of the boards indicated at 2, which may be composed of any suitablecheap material, as for instance, aper board, is of an area slightlylarger t an thatof the bundle end with which it is to be used. Thecorners of the board are notched as shown at 3, over a depthcorresponding to half the width of the excess material in one direction,so that four flanges 4 and. 5 are provided, one at each edge of theboard. The board is creased longitudinally and transversely on lines.extendmg between the corners of adjacent notches as indicated at 6, sothat the flanges l and-5 may be bent on the crease lines at an angle tothe plane is that of the bundle end, so that when the board is placedupon the bundle end, the flanges 4 and 5 will extend beyond the faces ofthe bundle, and may be bent down against such faces, as shown inFigure 1. V c i The binding strands indicated at 7 and- 8, and usuallyof wire, are so-arranged that they cross the boards transversely, andlongitudinally, and the ends of the wires are usually connected bytwisting the said ends together as indicated at 9. The number andarrangement of the tie or binding wires dc pendupon the size of theshingles and their arrangement 1 the bundle. Usually there is one strandc ossing the boards longitudinally, at the middle, and two strands crossing transversely near the ends of theboards.

A relatively light board will furnish suflicient protectlon for theshingles, but the. boards cut readily at the tiewires and somereinforcing means atthese points must be provided in order that thelight board give satisfactory service.

In order to provide a simple inexpensive, yet efiicient reinforce, aplurality of tongues 10 is formed in the board. These tongues arearranged in pairs transversely and longitudinally of the board, and onlines which when the boards are used, will be occupied by the tie wires.

The tongues are formed by slitting the boards on parallel spaced lines,and connecting the lines at one end. Each tongue is arextend beyond thecrease line andlap upon the adjacent flange 4 or 5 as the case may be.Thus each tongue reinforces the corner or angle between the board bodyand the flange at the point where the tie wire crosses, to preventcutting of the board at such point. Wherever a tie wire changesdirection, a

double thickness of the board is provided,-

without any cost for additional material. The provision of the tonguesadds nothing to the cost of the boards, since the cutting of thetongues, the notching of the corners, and the formation of the creaselines may be done simultaneously with the cutting of the board from asuitable web of material.

-With some character of shingles, only transverse binding strands areused and in such case the flanges 5 will be omitted, as well as thereinforcing tongues adjacent suchflanges. In fact any or all of theflanges may vbe omitted if desired, and the location of the reinforcingtongues will depend upon the location of the strands. Referring toFigure 3 it will be noticed that the tongues are creased or scored attheir junction with the body of the board, and also alongl the line uponwhich the will fold about t 0 corner of the bundle. sually a simplecrease line is suflicient, but with some character of board, it may benecessary to score the lines.

I claim: I

1. A binder board for shingle bundles and the like, creased near eachedge, the creases defining a substantially rectangular area approximatelthat of the bundle-end, the portions outsi e the creases forming flangesengaging the sides of the bundle, and tongues ormed from the boardadjacent to the crease I lines on the inner sides thereof and of alength to extend beyond the adjacent crease lines when bent outwardlyupon the board, said tongues arranged in pairs, the members board.

2. Binder boards for shingle bundles adapted to be arranged at the endsof the bundle and to be bound theretoand to each other by bindingstrands, each of said boards creased near each edge, to formflangesoutside the crease lines the flanges engaging the faces of thebundle, each board having tongues formed from the board adjacent to thepoints where the binding strands cross the crease lines, said tonguesbent outwardly and of a length to extend beyond the adjacent creaselines 3.

4. Binder boards for shingle bundles and the like, of an areasubstantially that of the bundle end andprovided with tongues of alength to extend beyond the end edges when '6. Binder boards for shinglebundles and the like, of an area substantially that of the bundle endand provided with tongues of a length to extend beyond the end edgeswhen said tongues are bent outwardly, said tongues arranged in pairslongitudinally and transversely of the boards, the board having a flangeat each edge to lap upon the Iadjacentface of the bundle, the tongueslapping on the flanges.

Binder boards for shing'le bundles and the like, having flangededges, and integral reinforcements for the corners at the points crossedby the binding strands for the bundle, the connections of thereinforcements with the body of the board spaced inwardly from thejunctions between the flanges and the body of the board, and of a lengthto extend across and beyond said junctions. Y
